Patented May a, 1916.

Application filed April 27, 1915. Serial No. 24,270.

ToaZZ whom it may concern Be it known that I, FRANK CLAYTON HER- BERT, acitizen of the United Kingdom of Great Britain and Ireland, and residentof Regents Park road, Regents Park, Lon

don, England, have invented certain new and useful Improvements inBottle-Stopper Devices, of which the following is a specification, suchas will enable others skilled in the art to which it appertains to makeand use the same.

This invention relates to a device for pre venting the fraudulentrefilling of bottles. The improved devicevis made in separate parts andcomprisesa hollow outer or case portion containing a guide and a weight,and an inner neck portion, a tight joint between the device and the neckof the bottle being obtained by means of a tubular washer of cork orother material whereby the use of cement is obviated. The tubular washerwhich may be in one or more parts also seals the device in the bottleneck.

If desired aiiat or disk valve may be placed between the weight and theupper end of the neck portion. I

The device may be made of porcelain or similar material or combinationof materials.

The invention will now be described with reference to the accompanyingdrawing, wherein liigure 1 shows a section through one of the improvedstoppers, and Fig. 2 shows a modification. v

Referring to the drawing wherein the same reference letters refer to thesame or similar parts, an is the outer or case portion which is attachedto the neck I) of a bottle by the metal sleeve 0 in substantially knownmanner.

To the lower end of the case is fitted a neck-part Z and washer e. Thiswasher serves to seal the line of junction between the end of the case aand the top of the neck .of the bottle and at the same time serves toseal the neck-part (Z in the bottle neck. The washer e is of tubularformation and is preferably tapered as shown to enable a very tight fitto be obtained. It may be made of cork or other suitable material,

and in one or more parts. Above the neckpart (Z is a disk valve andabove this valve is a conical weight f whose upper side 1s ribbed. Theweig t i is located beneath a guide 9 arranged within the case a. The gude is provided with a conical recess which corresponds substantially tothe conical portion of the weight and may be fixed to the case or may beloose. When the guide is loose the. inside of the case is preferablyribbed. The guide g is less in diameter than the internal diameter ofthe case a so as to form d scharge passages between.

it and the internal surface of the case a.

The valve is quite loose on its seat and remains seated when the bottleis in the upright position so that no adultera ts can be passed into thebottle but moves from its seat when the liquid container is turned. onits side thereby allowing the contents thereof to pass.

In the modification illustrated in Fig. 2 the end of the case. rests onthe upper edge of the tubular washer e and a ring washer h is also used.The ring'washer is shown separate from the tubular washer but may beintegral therewith.

The case is provided with a flange and a shorter meta-l sleeveisemployed.

A weight other than of conical shape may be used and the ribs may be onthe guide as well as or instead of on the weight.

What I claim and desire to secure by Letters Patentis:

1. The combination with a bottle neck of an outer casing resting uponthe top of the neck, a compressible tubular washer partly within ,thebottle neck and partly within the outer casing, a tubular portion Withinthp. {said washer, a weight above the said tubularrportion and anexternal sleeve for securing the outer casing to the bottle neck.

2. The "combination with a bottle neck of an outer casing resting uponthe top of the neck, a compressible tubular washer partly within thebottle neck and partly within the outer casing, a" tubular portionwithin the said washer, a weight above the said tubular portion, a diskvalve between the weight and the tubular portion and an external sleevefor securing thd'outer casing to the bottle neck. I

In witness whereof I have hereunto set my hand in presence of twowitnesses.
